    Abstract: The present disclosure provides for a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer (102) of a first hard restorative material having a first translucency and a first shade, a second layer (104) of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true: the first translucency is different from the second translucency, the first shade is different from the second shade. The first layer (102) and the second layer (104) form a first interface having a first curve (112) across a first plane of symmetry (114) of the dental mill blank, where the first curve (112) has a different from zero curvature; and a first straight line (122) along the entire length of a second plane (118) of the dental mill blank, the second plane (118) being orthogonal to the first plane of symmetry (114).

    Abstract: A multifunctional polymerizable ionic liquid is described comprising an anion and a cationic group having at least two ethylenically unsaturated polymerizable groups, each bonded to the cationic group via a divalent non-alkyl linking group. The multifunctional linking groups independently comprise a heteroatom such as oxygen or nitrogen. The linking groups may independently comprise one or more linkages such as an amide, urea, and more typically a urethane or ester linkage. The ethylenically unsaturated polymerizable groups are typically (meth)acrylate groups. Coatings and coated articles are also described.

    Abstract: Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.
